How does the CleO draw needles?

[mrclnz]

As shown in https://www.ftdichip.com/Images/CleO/CleO50-TutorialPics.png it seems the MCU on the CleO somehow coerces the FT810 into drawing tapered lines… how is that done?

- Multiple overlapping lines?
- Somehow changing line width between points?
- Magic?

Hello,

On CleO needles are in an built widget, if you wish to recreate a needle on a standard EVE module you can do so with bitmaps.
A base needle bitmap could be created (make sure to use a bitmap format which supports the alpha channel), this can then be coloured, rotated or scaled to suit your needs.

Oooh that's interesting. I've pondered about many ways to do it but not a bitmap. Thanks for the info
